【RT-Thread RISC-V 评估板】+ 上电，RGB流水灯走一个！

在源文件rgb.c中添加代码如下：#include "rgb.h"#include <rtthread.h>#include "board.h"
struct Led_s{    uint8_t LED_R;    uint8_t LED_B;    uint8_t LED_G;};      //define RGB struct
struct Led_s Led;
void RGB_Init(void){    //define Pin Number    Led.LED_R = rt_pin_get("PE.1");    Led.LED_G = rt_pin_get("PA.1");    Led.LED_B = rt_pin_get("PE.4");    //Set Pin Mode    rt_pin_mode(Led.LED_R, PIN_MODE_OUTPUT);    rt_pin_mode(Led.LED_G, PIN_MODE_OUTPUT);    rt_pin_mode(Led.LED_B, PIN_MODE_OUTPUT);}
//传入参数 on=1：对应亮，on=0:对应灭//红灯驱动void RGB_Red(rt_bool_t on){    rt_pin_write(Led.LED_G, PIN_HIGH);    rt_pin_write(Led.LED_B, PIN_HIGH);    if (on) {        rt_pin_write(Led.LED_R, PIN_LOW);    }else {        rt_pin_write(Led.LED_R, PIN_HIGH);    }}//蓝灯驱动void RGB_Blue(rt_bool_t on){    rt_pin_write(Led.LED_G, PIN_HIGH);    rt_pin_write(Led.LED_R, PIN_HIGH);    if (on) {        rt_pin_write(Led.LED_B, PIN_LOW);    }else {        rt_pin_write(Led.LED_B, PIN_HIGH);    }}//绿灯驱动void RGB_Green(rt_bool_t on){    rt_pin_write(Led.LED_R, PIN_HIGH);    rt_pin_write(Led.LED_B, PIN_HIGH);    if (on) {        rt_pin_write(Led.LED_G, PIN_LOW);    }else {        rt_pin_write(Led.LED_G, PIN_HIGH);    }}

在源文件rgb.h中添加代码如下：#ifndef RGB_H__#define RGB_H__#include <rtthread.h>void RGB_Init(void);void RGB_Red(rt_bool_t on);void RGB_Blue(rt_bool_t on);void RGB_Green(rt_bool_t on);#endif

在mian函数里面添加代码如下：#include <rtthread.h>#include "board.h"#include "rgb.h"
static void rgb_thread_entry(void* p){    RGB_Init();    while(1)    {      rt_thread_mdelay(1000);      RGB_Blue(1);      rt_thread_mdelay(1000);      RGB_Green(1);      rt_thread_mdelay(1000);      RGB_Red(1);    }}
static int Thread_RGB(void){    rt_thread_t thread = RT_NULL;    thread = rt_thread_create("rgb", rgb_thread_entry, RT_NULL, 512, 10, 10);    if(thread == RT_NULL)    {        rt_kprintf("Thread_GRB Init ERROR");        return RT_ERROR;    }    rt_thread_startup(thread);}
INIT_APP_EXPORT(Thread_RGB);
int main(void){
    while (1)    {        rt_thread_mdelay(1000);    }}
